Notes
- The discontinued Blue Arrow R08012MG is a premium, heavy-duty retract servo that enhances the standard retract design with the critical addition of a rugged, all-metal gear (MG) train. This servo is engineered for larger, heavier, and faster model aircraft where the landing gear system is subjected to significant stress. During a high-speed pass, the gear doors can experience high aerodynamic loads. During landing, especially a less-than-perfect one, the entire shock of touchdown is transmitted through the gear struts and into the retract mechanism itself. The metal gears of the R08012MG provide an essential layer of durability, ensuring the retract system can withstand these forces without stripping, which would leave the gear stuck in a dangerous, partially deployed state.
- The core benefit of the R08012MG is its sheer toughness. It is the retract servo of choice for pilots of scale warbirds, civilian airliners, and jets, where the landing gear is often complex, heavy, and a key part of the model's visual appeal and function. The peace of mind that comes from knowing the gear is actuated by a robust, metal-geared servo is invaluable. It ensures reliable, repeatable operation of the retract system flight after flight, protecting the significant investment in the airframe from damage caused by gear-up landings.
- In the robotics and automation fields, the R08012MG’s characteristics make it a unique and valuable component for high-stress, binary actuation. Its non-proportional, end-to-end travel combined with its extreme durability makes it ideal for industrial applications where a simple, robust on/off mechanism is needed. It could be used to operate heavy-duty latches on safety enclosures, actuate large pneumatic or hydraulic valves, or for any automated task that requires a simple but powerful and incredibly reliable two-position actuator that can withstand a harsh physical environment.
